Commentary on "Epigenome-wide analysis across the development span of pediatric acute lymphoblastic leukemia: backtracking to birth".

VTRNA2-1 is a polymorphically imprinted locus. The proportion of individuals with a maternally imprinted VTRNA2-1 locus is consistently approximately 75% in populations of European origin, with the remaining circa 25% having a non-methylated VTRNA2-1 locus. Recently, VTRNA2-1 hypermethylation at birth was suggested to be a precursor of paediatric acute lymphoblastic leukaemia with biomarker potential.

Molecular basis of JAK kinase regulation guiding therapeutic approaches: Evaluating the JAK3 pseudokinase domain as a drug target.

Janus kinases (JAK1-3, TYK2) are critical mediators of cytokine signaling and their role in hematological and inflammatory and autoimmune diseases has sparked widespread interest in their therapeutic targeting. JAKs have unique tandem kinase structure consisting of an active tyrosine kinase domain adjacent to a pseudokinase domain that is a hotspot for pathogenic mutations. The development of JAK inhibitors has focused on the active kinase domain and the developed drugs have demonstrated good clinical efficacy but due to off-target inhibition cause also side-effects and carry a black box warning limiting their use.

Unsupervised clustering reveals noncanonical myeloid cell subsets in the brain tumor microenvironment.

The tumor immune microenvironment (TiME) of human central nervous system (CNS) tumors remains to be comprehensively deciphered. Here, we employed flow cytometry and RNA sequencing analysis for a deep data-driven dissection of a diverse TiME and to uncover noncanonical immune cell types in human CNS tumors by using seven tumors from five patients. Myeloid subsets comprised classical microglia, monocyte-derived macrophages, neutrophils, and two noncanonical myeloid subsets: CD3 myeloids and CD19 myeloids.

Personalized Profiling of Lipoprotein and Lipid Metabolism Based on 1018 Measures from Combined Quantitative NMR and LC-MS/MS Platforms.

Applications of advanced omics methodologies are increasingly popular in biomedicine. However, large-scale studies aiming at clinical translation are typically siloed to single technologies. Here, we present the first comprehensive large-scale population data combining 209 lipoprotein measures from a quantitative NMR spectroscopy platform and 809 lipid classes and species from a quantitative LC-MS/MS platform.

Understanding lipidomics associations and the lipoprotein-related caveats in population epidemiology.

Mass spectrometry lipidomics is becoming customary to analyse serum/plasma samples in epidemiology. The measurables are molecular constituents of lipoprotein particles, but very little is known on the consequences of adjusting lipidomics data with lipoprotein measures. We studied two population cohorts with 5,657 and 2,036 participants.

Bioinformatic characterization of ENPEP, the gene encoding a potential cofactor for SARS-CoV-2 infection.

Research on SARS-CoV-2, the viral pathogen that causes COVID-19, has identified angiotensin converting enzyme 2 (ACE2) as the primary viral receptor. Several genes that encode viral cofactors, such as TMPRSS2, NRP1, CTSL, and possibly KIM1, have since been discovered. Glutamyl aminopeptidase (APA), encoded by the gene ENPEP, is another cofactor candidate due to similarities in its biological role and high correlation with ACE2 and other human coronavirus receptors, such as aminopeptidase N (APN) and dipeptidyl peptidase 4 (DPP4).

Associations of Cumulative Adulthood, Childhood and Life-long Insulin with Adulthood Retinal Microvasculature.

Context: Exogenous insulin is reported to have both vasodilatory and vasoconstrictive effects on the microvasculature. Little is known about the associations of long-term endogenous insulin exposure with microvasculature.

Objective: To test the hypothesis that long-term exposure to high insulin levels in childhood and adulthood is associated with adverse changes in retinal microvasculature in adulthood in a population without diabetes.

Circulatory miRNAs in essential hypertension.

MicroRNAs (miRNAs) are short non-coding RNAs, that regulate gene-expression at post-transcriptional level. Unlike other RNA species, blood miRNAs circulate in a highly stable form, either within extracellular vesicles or bound to proteins. In recent years, circulatory miRNA profiles have been proposed as potential biomarkers for multitude of pathologies, including essential hypertension.

Long-term Risk of Prostate Cancer Mortality Among Men with Baseline Prostate-specific Antigen Below 3 ng/ml: Evidence from the Finnish Randomized Study of Screening for Prostate Cancer.

Background And Objective: Despite the evidence for prostate-specific antigen (PSA) screening reducing prostate cancer (PCa) mortality, the optimal PSA cutoff and the clinical significance of low initial PSA levels in predicting long-term PCa mortality remain subjects of ongoing research. We assessed PCa mortality among men with initial PSA levels below 3 ng/ml during the first screening round of the Finnish Randomized Study of Screening for Prostate Cancer (FinRSPC).

Methods: A retrospective cohort study was conducted, including 20 268 men from the screening arm of the FinRSPC with an initial PSA level of <3 ng/ml, with follow-up spanning up to 20 yr.

Blood metabolomic profiling reveals new targets in the management of psychological symptoms associated with severe alcohol use disorder.

Background: Alcohol use disorder (AUD) is a global health problem with limited therapeutic options. The biochemical mechanisms that lead to this disorder are not yet fully understood, and in this respect, metabolomics represents a promising approach to decipher metabolic events related to AUD. The plasma metabolome contains a plethora of bioactive molecules that reflects the functional changes in host metabolism but also the impact of the gut microbiome and nutritional habits.

Efficient Search Algorithms for Identifying Synergistic Associations in High-Dimensional Datasets.

In recent years, there has been a notably increased interest in the study of multivariate interactions and emergent higher-order dependencies. This is particularly evident in the context of identifying synergistic sets, which are defined as combinations of elements whose joint interactions result in the emergence of information that is not present in any individual subset of those elements. The scalability of frameworks such as partial information decomposition (PID) and those based on multivariate extensions of mutual information, such as O-information, is limited by combinational explosion in the number of sets that must be assessed.

Clinical performance of two commercially available rapid antigen tests for influenza, RSV, and SARS-CoV-2 diagnostics.

Unlabelled: Rapid antigen tests (RATs) might provide rapid, low-cost, and easy-to-perform choice to nucleic-acid amplification methods (NAAT) in point-of-care (POC) diagnostics of respiratory infections. The clinical performance of two commercial combo-RATs for influenza A and B, respiratory syncytial virus (RSV) and severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) POC diagnostics, was assessed. RAT and real-time-PCR (RT-PCR) analysis were performed on 620 patients admitted to the emergency department due to respiratory symptoms.

Here, we aimed to evaluate the most essential molecular factors, such as IDH (isocitrate dehydrogenase) mutation in gliomas classification with patient-derived glioma organoids (PGOs) using differential mobility spectrometry (DMS).

Methods: we prospectively recruited 12 glioma patients, 6 IDH-mutated and 6 IDH wild-type tumors, from which PGOs were generated ex-vivo.

Micro-computed Tomography in the Evaluation of Eosin-stained Axillary Lymph Node Biopsies of Females Diagnosed with Breast Cancer.

Histopathological investigation of metastasis in core needle axillary lymph node (ALN) biopsies is crucial for the prognosis and treatment planning of breast cancer patients. Biopsies are typically sliced and evaluated as two-dimensional (2D) images. Biopsy sampling errors and the limited view provided by 2D histology are leading factors contributing to false-negative results in the preoperative detection of metastatic lymph nodes and underestimation of metastatic foci.
